Council Speaker Corey Johnson accused officials of a Manhattan homeless shelter operator Wednesday of giving “dozens of seniors a real lump of coal” during the holidays by announcing the closure of their housing complex to cash out and sell the building.

The Riverview Senior Independent Center is located in Johnson’s district in Hell’s Kitchen.

The owner of the Riverview facility — the not-for-profit Independent Institute for Children and Poverty Foundation or ICPH — is an affiliate of Homes for the Homeless.

The Riverview owners “decided to give dozens of seniors a real lump of coal during the holidays and tell them they only have a few months to relocate their lives,” Johnson fumed Wednesday during a City Hall press conference.

The Post broke the story Tuesday on the group’s Scrooge-like announcement.

Johnson said he’s talked to state Attorney General Letitia James — whose oversees not-for-profit/charitable groups — to investigate the pending closure and sale of the Riverview building.

“I spoke to the attorney general today, and she is all over this,” he said.

“I think that if you’re an organization whose name is Homes for the Homeless and you’re going to make people homeless who are senior citizens, one is a 99-year-old Holocaust survivor, it doesn’t seem right to me. It looks like they’re trying to capitalize on a significant real estate value on the west side of Manhattan, and while they’re doing so they’re going to displace a huge number of senior citizens.”

Johnson continued, “I want to make sure that we are protecting the senior citizens. This is inhumane to do this around the holidays. Ultimately, we want to keep these people in place, so we are looking at solutions on how to do that.”

“They should be ashamed. It is shameful to scare senior citizens and announce this in the midst of the holiday season.”

He and other pols also sent a joint letter to Homes for the Homeless CEO Ralph Nunez to express their outrage and demand a meeting.

The co-signers include Congressman Jerrold Nadler, state Sen. Brad Hoylman, Manhattan Borough President Gale Brewer and Assemblywoman Linda Rosenthal.

A rep for the Homes for the Homeless ICPH affiliate defended the group’s decision to shut the facility and put the 15-story building at 519 West. 49th Street near Tenth Avenue up for sale.

The facility attracted only 31 tenants and was operating at a huge deficit, said Riverview spokeswoman Linda Bazerjian.

“We can’t afford to run it,” she said.

Bazerjian said the operator felt obliged to tell tenants about their intention to sell the building as soon as possible.

“Residents will not be homeless. Nobody is going to be homeless,” Bazerjian said.

She said Riverview staff will meeting with tenants individually to help each of them relocate, including to a senior housing center the group runs on Staten Island.

Johnson called Riverview’s claim that it couldn’t find tenants to fill the building “shocking to me.”

“There are wait lists all around the city for affordable housing generally. There is a significant lack of senior affordable housing in New York City, so I don’t know how they are trying to find seniors but there are plenty of seniors who need homes … I find it hard to believe that they aren’t able to find people to live in this great location in this great building,” he said.

Homes for the Homeless formerly operated the building in the gentrifying neighborhood as a transitional shelter for homeless families for 20 years before shutting it down and converting it into a housing complex for seniors.
